Description
Technical field
The utility model relates to motor production equipment field, particularly relates to a kind of servo motor rotor iron core riveting frock.
Background technology
Rotor core is stacking according to certain rule by rotor punching (0.35mm or 0.5mm silicon steel sheet), connects, then flatten manufactured head with hydraulic press with rivet, makes rotor punching be stacked into rotor core, and rivet connects the structural strength that has also guaranteed rotor core simultaneously.
Yet, because rotor punching edge is jagged, cause actual stacks as high to be greater than theoretical stacks as high, make rivet point stretch out rotor core part and cannot get to theoretical length.If stacks as high is not processed, blindly, after compacting, can cause rivet crooked in rotor core, thereby cause rotor core notch uneven, rotor core is scrapped.
At present conventional processing method be by, first with bolt, compress upper and lower two block pressur plates, thereby the actual stacks as high that guarantees rotor punching equals theoretical stacks as high, make rivet point stretch out rotor core and reach theoretical length, with hydraulic press, suppress again, thereby rivet point is driven plain, compresses rotor punching, produce qualified rotor core.But owing to making the method that is tightened by bolts rotor core need a lot of time to operate, and while locking bolt, all need frock to take out very effort from hydraulic press at every turn, production that cannot be time saving and energy saving, this with enhance productivity, reduce labour cost, reduce labour intensity and disagree.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of servo motor rotor iron core riveting frock, simple in structure, easy to operate, and effectively deburring, has improved production efficiency greatly.
The utility model solves the technical scheme that its technical problem adopts: a kind of servo motor rotor iron core riveting frock is provided, comprise base plate, fixed head and plug, described base plate is in the form of annular discs, its upper end is connected and installed with columniform fixed head, described plug is arranged between two parties the upper end of base plate and passes from fixed head upper end, the upper surface of described fixed head is furnished with several stage clips along even circumferential, the upper end of described stage clip is connected with lower platen, the upper surface of described fixed head is provided with several thimbles, position corresponding on the lower platen of this thimble upper end has through hole, described plug passes its upper end from lower platen centre and is connected with top board.
The position of described thimble is corresponding with the rivet of rotor core lower end with quantity.
Described stage clip separates one end distance by lower platen jack-up and fixed head.
The internal placement of described top board has step, and described plug and this step withstand.
The top of described thimble when the laminating of lower platen and fixed head lower than the upper surface of lower platen.
Described stage clip is the cylinder-shaped compression spring of square-section.
The upper surface area of described lower platen is greater than the cross-sectional area of rotor core.
The shape of the centre bore of the profile of described plug and size and rotor core matches.
Because stage clip has elastic force after compressed, its equation F=kx, wherein, F is elastic force, K is spring ratio, and X is the distance that departs from balance point, so it is larger to work as the compressed distance of spring, elastic force is larger, when elastic force is greater than the crush resistance of rotor punching burrs on edges, burr is driven plain or extrudes, and makes the actual stacks as high of rotor punching equal theoretical stacks as high, thimble the afterbody exposing of rivet can be flattened and diameter increases, thereby forms a complete rotor core.
beneficial effect
The utility model relates to a kind of servo motor rotor iron core riveting frock, simple in structure, easy to operate, utilize the pressure of stage clip rotor core to be compressed and removed burr, simultaneously thimble can flatten the afterbody exposing of rivet and the rotor core of diameter after increasing to be fixed and clamped, time saving and energy saving, greatly improved production efficiency.

Fig. 2 is perspective view of the present utility model;
Fig. 3 is the plan structure figure of lower platen described in the utility model;
Fig. 4 is that master of the present utility model looks sectional structure chart.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment are only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after having read the content of the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
As Figure 1-4, execution mode of the present utility model relates to a kind of servo motor rotor iron core riveting frock, comprise base plate 1, fixed head 2 and plug 4, described base plate 1 is in the form of annular discs, its upper end is connected and installed with columniform fixed head 2, described plug 4 is arranged between two parties the upper end of base plate 1 and passes from fixed head 2 upper ends, the upper surface of described fixed head 2 is furnished with several stage clips 6 along even circumferential, the upper end of described stage clip 6 is connected with lower platen 3, the upper surface of described fixed head 2 is provided with several thimbles 7, on the lower platen 3 of these thimble 7 upper ends, corresponding position has through hole 10, described plug 4 passes its upper end from lower platen 3 centres and is connected with top board 5.
The position of described thimble 7 and quantity are corresponding with the rivet 9 of rotor core 8 lower ends.
Described stage clip 6 separates one end distance by lower platen 3 jack-up and fixed head 2.
The internal placement of described top board 5 has step 51, and described plug 4 withstands with this step 51.
The top of described thimble 7 is in lower platen 3 upper surface lower than lower platen 3 during with fixed head 2 laminating.
The cylinder-shaped compression spring that described stage clip 6 is square-section.
The upper surface area of described lower platen 3 is greater than the cross-sectional area of rotor core 8.
The shape of the centre bore of the profile of described plug 4 and size and rotor core 8 matches.
This frock fluid,matching press uses, and base plate 1 is placed on hydraulic press workbench, takes down top board 5, by the punching centre bore of a certain amount of rotor core 8, and has remembered groove alignment, aims at plug 4 and fills in;
In rotor core 8 rivet holes, insert rivet 9, cover top board 5, primer fluid press presses down, when hydraulic press upper table plate contact top board 5, because rotor core 8 is now in loose condition (of surface), and stage clip 6 is in poised state, so the first rotor driven iron core 8 of meeting, rivet 9 and lower platen 3 press down, when stage clip 6 compression distances increase, elastic force increases, and rotor core 8 can be gradually compacted, until rotor core 8 reaches theoretical length, now rivet 9 afterbodys can expose in the lower end of rotor core 8, reach requirement length;
Hydraulic press continues to press down, and when rivet 9 afterbodys run into thimble 7, rivet 9 afterbodys that expose rotor core 8 can be driven plain and diameter increase, make rivet 9 tightly fasten end to end rotor core 8, rotor core 8 has been produced, and hydraulic press continues to press down, when lower platen 3 touch fixed head 2, compacting finishes;
After compacting finishes, pin hydraulic press and return switch, unclamp hydraulic press pressing plate, now stage clip 6 can recover original length gradually, and jack-up lower platen 3, product 8 and top board 5, after hydraulic press is return completely, take out top board 5, then take out rotor core 8, the now production of rotor core 8 finishes completely.
